Tanning bed bulbs and lamps should be replaced when they have been used to 80 percent of their expected life cycle, and typically hit this mark about one year after they have been installed. Low-pressure lamps have a life cycle of 300 to 1,700 hours, while high-pressure bulbs last 300 to 9,500 hours.
Think about the number of lights in your house â some fixtures, like chandeliers or ceiling fans, probably even use three bulbs or more. If you replaced 20 incandescent bulbs with LED light bulbs throughout your home, you could save up to $3,260 over their 23-year lifespan (and thatâs assuming utility rates donât rise). Still, you donât even have to make that big of a commitment to realize some significant savings.
